Comprehensive Summary Inflammation is associated with different stages of liver disease, including acute injury, fibrosis, cirrhosis, and hepatoma. During the progression inflammation, activation hepatic stellate cells (HSCs) extracellular matrix (ECM) deposition are critical pathologies, thus combined therapy using HSCs ECM as targets represents a promising strategy in treatment injury. Here, novel CXCR4‐inhibiting nanomedicine that can simultaneously deliver AMD3100 (CXCR4 antagonist) siPAI‐1 (siRNA plasminogen activator inhibitor‐1) was designed developed to reverse fibrosis by inhibiting degrading deposition. With this goal mind, Zn(II) coordinated polymeric named PAMD/Zn polymer siRNA delivery CXCR4 antagonism capabilities synthesized. Overall, our results suggest recruits pro‐inflammatory for fibrogenesis inhibits fibrolysis at various Its use conjunction PAI‐1 silencing achieved satisfactory therapeutic efficacy injury fibrosis.

Abstract Inducing cell migration from the edges to center of a wound, promoting angiogenesis, and controlling bacterial infection are very important for diabetic wound healing. Incorporating growth factors antibiotics into hydrogels dressing is considered potential strategy meet these requirements. However, some present drawbacks greatly slow down their development toward application, such as short half‐life high price factors, low antibiotic efficiency against drug‐resistant bacteria, insufficient ability promote migration, etc. Deferoxamine (DFO) can upregulate expression HIF‐1α, thus stimulating secretion angiogenesis‐related endogenous factors. Copper sulfide (CuS) nanoparticles possess excellent antibacterial performance combined with photothermal therapy (PTT). Herein, DFO CuS incorporated biomimetic hydrogel, which mimics structure function extracellular matrix (ECM), abbreviated DFO/CuS‐ECMgel. This hydrogel expected be able adhesion degraded by cell‐secreted metalloproteinases (MMPs), then release at site exert therapeutic effects. As result, three crucial requirements healing, “beneficial effectively killing bacteria,” achieved simultaneously.

The performance and reliability of machine learning (ML)-quantitative structure-property relationship (QSPR) models depend on the quality, size, diversity data set used for model training. In this study, we manually curated a large-scale containing 3120 donor-acceptor (D-A) conjugated polymers (CPs) by selecting most utilized 60 donors 52 acceptors. This serves as valuable resource ML-based prediction key electronic properties such band gap energy (Eg) hole reorganization (λh), calculated using density functional theory (DFT) to advance organic photovoltaics (OPV). Beyond construction, systematically investigated how different descriptor fingerprint types impact ML model. Recognizing that not all features contributed equally performance, conducted an in-depth analysis identify informative descriptors fundamental optoelectronic properties. Our findings show kernel partial least-squares (KPLS) regression utilizing radial molprint2D fingerprints achieved highest accuracy in predicting Eg, with R2 values 0.899 0.897, respectively. For λh prediction, integrating frontier orbital levels significantly improved achieving value 0.830. study provides comprehensive investigation influence OPV research.
